What's the difference between constraint and requirement?

Constraint


Definition:

  • (n.) The act of constraining, or the state of being constrained; that which compels to, or restrains from, action; compulsion; restraint; necessity.

Example Sentences:

  • (14) For one, the ability to raise a larger deposit is acting as a constraint.
  • (15) When the constraints are high, a Michaelis-Menten equation can be used to model the kinetics for interfacial concentrations lower than the concentration leading to the maximum reaction rate.

  • (17) A careful reorganization of priorities would thus be helpful in improving neonatal care in Jamaica, even in the presence of financial constraints.
  • (18) Emergence and spread of antibiotic-resistant bacteria is augmented in settings in which treatment may be inadequate because of socioeconomic constraints and where there is crowding and poor sanitation.
  • (19) The estrogen receptor seems to have a moderate tolerance for bulky substituents: All of the halogen and halomethyl substituents bind with an affinity at least 50% that of estradiol; in the three atom alkyl series, the affinity declined markedly from propargyl (44%) and allyl (38%) to propyl (5%), suggestive of detailed steric constraints or a preference for unsaturation.
  • (20) Bias is controlled by the use of least-squares curve fitting for all assays, and constraints on the elimination of outlier points.

Requirement


Definition:

  • (n.) The act of requiring; demand; requisition.
  • (n.) That which is required; an imperative or authoritative command; an essential condition; something needed or necessary; a need.

Example Sentences:

  • (1) A 2.5-month-old child with cyanotic heart disease who required long-term PGE1 infusions; developed widespread periosteal reactions during the course of therapy.
  • (2) Patients with normal echocardiogram and ECG on admission do not require intensive care monitoring.
  • (3) More than 2 months after the combined treatment were required for the suppression.
  • (4) It involves creativity, understanding of art form and the ability to improvise in the highly complex environment of a care setting.” David Cameron has boosted dementia awareness but more needs to be done Read more She warns: “To effect a cultural change in dementia care requires a change of thinking … this approach is complex and intricate, and can change cultural attitudes by regarding the arts as central to everyday life of the care home.” Another participant, Mary*, a former teacher who had been bedridden for a year, read plays with the reminiscence arts practitioner.
  • (5) Blatter requires a two-thirds majority of the 209 voters to triumph in the opening round, with a simple majority required if it goes to a second round.
  • (6) In platform shoes to emulate Johnson's height, and with the aid of prosthetic earlobes, Cranston becomes the 36th president: he bullies and cajoles, flatters and snarls and barks, tells dirty jokes or glows with idealism as required, and delivers the famous "Johnson treatment" to everyone from Martin Luther King to the racist Alabama governor George Wallace.
